Solve : What has my psu got on the 12 volt rail??

Answer»

I have a CoolerMaster 650 watt and would like to KNOW where I look to see what is on the 12 volt rail?  I am looking at this psu and don't see anything mentioning the word rail. THANKS!!

Ok I have now looked on the side and seen this diagram below. Does this mean I have 36 AMPS on the 12v rails? Or does the 0.8 under -12v COUNT for anything?

Ac input                                           220v-230v/6.3 50/60Hz
DC OUTPUT      +3.3v  +5V    +12V1   +12v2    -5V       -12V    +5Vsb
MAX.OUTPUT    28A     30A      18A       18A       0.8A     0.8A     2.0AAppears to have two +12V "rails".  Each one is 18A.  -12V is not used for much of anything anymore.
